To improve the efficiency of Chinese similarity computing, this paper gives a Chinese similarity computing system model in accordance with the problems of Chinese sentence similarity computation aspect. This model is a combination of punctuations and traditional similarity computing. Comparing with Cosine-based Similarity calculation, the sentence similarity calculation based on word shape and word order, and Sentence similarity calculation based on semantic, this model makes up their insufficiency to a certain extent. The experiment shows that this model has a higher rate of accuracy in Chinese similarity computing.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

The main idea is that, on one hand, we analysis the documents selected by user and use the knowledge of Formal Concept Analysis to construct a user concept lattice; on the other hand, we find some documents which are different from the documents mentioned above and build another concept lattice. Then we calculate the concept similarity through a novel method to identify the concepts which have higher similarity with the user concept lattice. Finally, we extract the extension of these concepts and add them to the user document set; consequently we can optimize the query expansion source. The experiment results show that our method is quite reasonable.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

The performance is evaluated using Intel IXP2400 NP Simulator. The results demonstrate that, Active Network based Active Queue Management has better performance than RED algorithm and is well suited to achieve high speed packet classification to support multimedia applications with minimum delay and Queue loss. Using simulation, we show that the proposed system can provide assurance for prioritized flows with improved network utilization where bandwidth is shared among the flows according to the levels of priority. We first analyze the feasibility and optimality of the load distribution schemes and then present separate solutions for non-delaysensitive streams and delay-sensitive streams.
